FOUNTAIN TOOTHBRUSH.

'Application filed December 4, l'1925. Serial No. 73,158.

This invention relates to a fountain tooth brush.

The object of the invention is the production of afountain tooth brush having a hollow handle for a collapsible` tube with paste and the like. The second object .of the invention is the production of a fountain i 4tooth brush with its handle reduced to small i its entirety dimensions. The third object ot the invention is the .production of a tooth brush, in,

which the outlet openings for its paste can be easily closed. The `fourth object of the invention is thel production of a fountain brush with parts that are easily disconnected.

l rlhe fifth object ofthe invention is the production of atooth brush that can be easily carried in the pocket of the user. The sixth object of the invention is the production `ot -a tooth. brush to be used withy a den tifrice and other material, which will be economicalin the use of said dentifrice or other material.` The seventh object' of the invention is the production of aI /ountain tooth brush, with bristles disposed in an In the accompanying drawings Fig. 1 represents a partial elevation and partial axial-section as on the line 1-1 of Fig. 2 of an eXemplificat-ion of the improved fountain tooth brush; Fig. 2 vshows a partial' top plan view and section of Fig. 1 on the line 2-2; Fig. 3 indicates anenlarged section of Fig, 2 on the line 3 3; Fig. 4 repdicates an enlarged lpartial section of Figi .1 on the line 6 6;

opening 26 and the shouldered end 27. The shouldered end 27 of said cap is normally located, in clamped position with the shouldered end 22 of the shell 21. An elliptical shaped front cap 30, has formed therewith the shouldered end 31, which is normally located in clamped position with the shoul ered end 23 of the shell 21. The shank of the tooth brush is indicated in its entirety at 34 and com rises the cylindricaly tubular portion 35,.wit `the cap 25 'has formed guide opening 36 and joins with theU- 'shaped tubular portion having the side members 37. A 'seat 38'having discharge openings 38a and dovetailed guides 39 are formed with said U shaped portion. An elliptical shaped flange 45 is formed at one end of the shank 34. The other end 46 of the shankv 34 is spherical shaped', and has formed therein the small opening A47. The flange 45 isdetachably connected to the front. cap 30 by means ot the screws 49. At i one end of the shell 21 is located the journal bearing bracketw', which has extending therefrom the lugs 56. The latter bear against the inner face of the shell 21 and are fastened thereto by means of the screws 57. At the other end of the shell 21 are detachably fastened the journal brackets 58, by

meansof the screws 59. Screws 6() and 61 have theirshanks at their ends respectively ]ournaled in the journal .brackets 55 and 58.. A pinion 62 is .fastened to each of the Screws and 61. A spur gear 63 is fastened to one end of lthe pin'-64 and the latter is journaled in the bracket 55, and to the other end of said pin is fastened the operating knob 65. l x

Within the trontcap 30 is fastened the supporting bracket 70, with the tapered seat 71 and the flanges 72. The latter are detachably fastened to the front cap 30, by means of the screws 73.

A pair of cross heads 75 and 76 are re-l spectively in threaded engagement with the screws 60 and 61. A pair of similar spindles77 have their endsjonrnaled in said cross heads and each is provided with the roller 78. Acylindrical tube.80 is slidably located in the shankl 34 and has yextending therefrom the adjusting knob 81, which lat'- ter extends through the guide opening 36 in the cylindrical tubular portion 35 of the shank of the brush. Outlet openings 82, 83, and 84 are formed in the tube 80.

An inner pipe86, closed .at one end of its ends 87 and Vwith a funnel shaped inlet openin 88 at its other end, is located within the tu '80. 4Adjacent to its opening` 88 it has formed therewith the external threads 89, which engage an axial threaded opening in the cap 30. Openings 90, 91, and 92 are formed in the pipe 86 in the longitudinal direction thereof.

f A slidable cap 95 has formed `therewith the dovetailed portions 96, which engage supl the` dovetailed guides 39. Tubular i portsu each with the npprtapered-*portion 97 and the flange 98 at'its lowerj end, are journaled in openings in the cap 95. The openings 99V in each of said supports" 'can engage. with the openings 82, 83, 84 ,and 90, 91 and 92. Bristles 100, arel clam ed between the tapered portions 97 and t e conical sleeves 101, which latter are held in place by rivets andwhich locate 'the rubbing tube 100 is inserted between the rollers -78;

The cap hs thenpagain located inv place on the shell 21,- and the funnel shaped outlet end 106 of ythe tube 105-is located on the tapered seat 71, while the-nipple 107 ,of the tube'is brought to bear. against the funnel shaped inlet opening 88 o f the inner v pipe 86. The tube 80 is located, by means of the adjusting-knob 81 to bring'its outlet openings82, 83 and 84 in line with the openings 90, 91 and 92 of the pipe.86.` Then to discharge some of the paste from the tube 105 and charge the bristles .99 therethrough the interposed gears.-

with, the user turns the'knob 65, by means of which the screws 60" and and 61 turn By this means the cross heads '7 5 and 76 are moved toward the shank 34 of the brush and the paste is forced from the tube 105 by collapslngfthe same, by virtue of the movelment and rotation of the rollers 78.

The 'paste enters the pipe 86 and is directed to the bristles 100. lVhen the tooth; brush is not in use the tube 80 is moved, hy means of the knob-81, to close the Upenings therein with respect to the openings 90,V 91v and 92 of the pipe 86. The opening 47 prevents an air cushion in the shank of the tooth brush when the tube 80 is moved toward its outer end. It will be noted that the tubular supports having theu n knob extending from said tube extending openings 99 are journaled to the cap 95 and that they therefore can turn when .the tooth brush is being used,lbut they cali betightly fitted in the cap 95 to prevent them turning. It; will be noted that when the brush is not in use the cover 102 is located inl, place to maintain the shank' 34, the bristles 100 andlrtheir appurtenances clean. i
